Problems solved by technology

At present, in addition to the high degree of automation of pipe welding for domestic and foreign rotary parts, most industrial parts are completed by manual and semi-automatic welding. Manual welding is greatly affected by human factors, and the production efficiency is low and the quality is difficult to guarantee.

Abstract

The invention discloses a rotary body part automatic argon arc welding device. The welding device is composed of a mechanical part, an electric control part and a pneumatic control part, and mainly comprises an electrode holder, an electrode holder clamp, a wire feeder, a rotary servo motor, a wire feeding servo motor, a telescopic air cylinder, a sliding table air cylinder and the like. During work, the telescopic air cylinder presses and positions a workpiece needing to be welded, then an argon switch works, the sliding table air cylinder moves forwards to enable a welding wire and the workpiece to be welded, meanwhile, the rotary servo motor and the wire feeding servo motor rotate synchronously, after the rotary servo motor rotates by one circle, the sliding table air cylinder retracts,argon supply is stopped, and welding is completed. The welding device is accurate in control and high in automation degree, and can meet requirements of different welding beads.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to an automatic argon arc welding device for rotary parts. Background technique [0002] Argon arc welding is an arc welding method that uses inert gas-argon as the shielding gas. The argon gas ejected from the nozzle creates a thick and dense gas shield in the welding area, which isolates it from the air. Under the protection of the argon gas laminar flow, the arc is used between the electrode (tungsten electrode or welding wire) and the workpiece. The heat generated by combustion melts the place to be welded, and fills or does not fill the welding wire, and connects the separated metals into one, so as to obtain a strong welded joint. [0003] The argon arc welding automatic welding device for the new truck filter assembly (rotary parts) needs to ensure that only carbon dioxide and water are contained in the exhaust emissions of the truck, which meets the requirements of environ...
